Day 2: slight mark where the paper covered the leaf; it is a lighter green than the rest of the leaf.
Day 4: yellow circle where the construction paper was.
Day 7: almost white circle where the paper covered the leaf.
Using your knowledge of photosynthesis, which answer choice explains what most likely will happen to those leaves once the plant is put back in the sun without the construction paper circles attached?
• Those leaves will fall off and the rest of the plant will continue to grow and perform photosynthesis.
•The rest of the plant will develop yellow or white circles just like the leaves that had the construction paper circles on them and photosynthesis will not occur in those areas even though the sunligh energy is being
absorbed by the chlorophyll contained in the chloroplasts.
The plant will die because the damage caused by the construction paper circles prohibited photosynthesis to occur at all.
Those areas that were covered by the paper circles will now be able to absorb the sunlight energy into the O chlorophyll contained in the chloroplasts, photosynthesis will occur in those areas, and the green color will
eventually return.
• The rest of the plant will develop yellow or white circles just like the leaves that had the construction paper circles on them and photosynthesis will not occur in those areas even though the sunlight energy is being absorbed by the chlorophyll contained in the chloroplasts.
The correct answer is: Those areas that were covered by the paper circles will now be able to absorb the sunlight energy into the chlorophyll contained in the chloroplasts, photosynthesis will occur in those areas, and the green color will eventually return.
Based on the information provided, the most likely answer choice is: "Those areas that were covered by the paper circles will now be able to absorb the sunlight energy into the chlorophyll contained in the chloroplasts, photosynthesis will occur in those areas, and the green color will eventually return."
To arrive at this answer, we need to understand the process of photosynthesis. Photosynthesis is the process by which plants convert sunlight energy into chemical energy, producing glucose and releasing oxygen as a byproduct. This process takes place in the chloroplasts, which contain chlorophyll, the green pigment responsible for absorbing light.
From the given observations, it is evident that the construction paper circles blocked sunlight from reaching the underlying leaves. As a result, the leaves had a lighter green color, and over time, the areas covered by the circles turned yellow and then almost white. These changes indicate a lack of photosynthesis in those areas.
Once the plant is put back in the sun without the construction paper circles, the blocked areas will now be exposed to sunlight. This will allow the chloroplasts in those areas to absorb light energy, and photosynthesis can resume. As a result, the green color will eventually return to those areas, indicating the production of chlorophyll and the occurrence of photosynthesis.
Therefore, the most likely outcome is that the areas covered by the construction paper circles will regain their ability to perform photosynthesis, and the green color will return.
